NuScale Power, LLC (NuScale) along with Shell Global Solutions (Shell) and industry participants will develop and assess a concept for an economically optimized Integrated Energy System (IES) for hydrogen production using electricity and process heat from a NuScale VOYGR™ small modular reactor (SMR) power plant. NuScale’s flexible SMR technology holds the potential to balance and stabilize power grids dominated by renewable energies through hydrogen production. Hydrogen would be used as an end-product or as a stored energy source to be processed through a Reversible Solid Oxide Fuel Cell (RSOFC) for electricity generation.
A NuScale control room simulator will be modified to evaluate the dynamics of the IES and will include models for the Solid Oxide Electrolysis Cell (SOEC) system for hydrogen production. The research will consider the number of NuScale Power Modules™ needed for use in SOEC hydrogen production and the quantity of hydrogen stored for subsequent electricity production.
